To the mind of an American, the idea of signing a contract as one thing but later being able to declare that you're really something else is vague and baffling. The fact that there had already been a lawsuit involving PJ's company dealing with this, and the ruling flip-flopped a couple times might be seen as an open door for problems in the future.

It WAS a cause for concern and I can understand WB or PJ or individual actors being concerned. Legal costs far into the future can be estimated I suppose but not budgeted and thus they can throw a monkey wrench into a company's or production's or an individual's budget planning. The only people that really win in the case of legal ambiguity are the lawyers. The clearer the law is the better it is for those who are trying to abide by it. If I were to consider being an actor in New Zealand, it would be nice to know clearly where I stand legally.
